Erosion control measures are required for construction areas where the ground surface will be disturbed by clearing, demolition, storage, grading, fills, exca vations and other construction and related activities.
26 Φεβ 2020 · Key Points. Hurricane Maria caused immediate beach loss of 3 to 5 m in Puerto Rico, with very large local disparities. Sentinel 1 synthetic aperture radar (SAR) can accurately monitor shoreline changes in cloudy conditions. Causal attribution of beach erosion to a specific storm is achieved using a regression discontinuity approach. 1 Introduction.
22 Ιουν 2022 · The island of Puerto Rico is subject to numerous natural hazards including hurricanes and coastal erosion. Information on how the island’s coastal environments respond to these events is critical for bolstering coastal resilience.
1 Ιαν 2012 · First, coastal communities in Puerto Rico have historically opted for various types of shore-hardening structures in order to prevent further shoreline retreat, even though such structures may enhance lateral shoreline erosion and disrupt natural beach cycles.
The state of erosion, accretion, or stability of the beach is identified on the interactive map with transects (lines perpendicular to the coastline) colored red (erosion), light green (accretion), and yellow (stability/no change) for the period of September 2017 and July 2018.
The municipalities with the most rigid structures on their coasts are: Fajardo, Mayagüez, Cataño and Dorado, suggesting that several of these rigid structures could have an impact or control on beach erosion/accretion processes.
The objectives associated with this goal are: 1) identify coastal types distribution; 2) assess shoreline changes between 1970’s and 2010 in Puerto Rico coastline, to identify erosion, accretion and no changes shoreline sites in Puerto Rico; 3) identify beach sites with major erosion problems for this period (20 sites); and 4) study subaerial b...
